ELONGATED MEDICAL NEEDLE
An elongated medical needle defines an open lumen presenting a distal face configured to be maneuvered toward, and positionable proximate to, the biological feature of the patient. A lid assembly is configured to selectively cover, at least in part, the distal face of the open lumen. The lid assembly is also configured to selectively emit energy toward the biological feature.
1 . Apparatus for use with a biological feature of a patient, the apparatus comprising:
an elongated medical needle defining an open lumen presenting a distal face configured to be maneuvered toward, and positionable proximate to, the biological feature of the patient; and
a lid assembly configured to selectively cover, at least in part, the distal face of the open lumen; and
the lid assembly also configured to puncture through the biological feature; and
the lid assembly also configured to selectively uncover, at least in part, the distal face of the open lumen after the lid assembly has punctured through the biological feature.
2 . The apparatus of claim 1 , wherein:
the elongated medical needle is configured to house the lid assembly.
3 . The apparatus of claim 1 , wherein:
the lid assembly includes a mechanical puncturing portion.
4 . The apparatus of claim 1 , wherein:
the lid assembly includes an active surface.
5 . The apparatus of claim 1 , wherein:
the lid assembly is configured to be selectively movable from a covering position to an exposing position in which the lid assembly exposes, at least in part, the distal face of the open lumen in such a way that the lid assembly, in use, permits selective fluid communication between the open lumen and the biological feature after the lid assembly, in use, selectively exposes, at least in part, the distal face of the open lumen.
6 . The apparatus of claim 1 , wherein:
the lid assembly is operatively mounted at the distal face of the open lumen of the elongated medical needle.
7 . An apparatus for use with a biological feature of a patient, the apparatus comprising:
an elongated medical needle defining an open lumen presenting a distal face configured to be maneuvered toward, and positionable proximate to, the biological feature of the patient; and
a lid assembly configured to selectively cover, at least in part, the distal face of the open lumen; and
the lid assembly also configured to selectively emit energy toward the biological feature after the distal face has been maneuvered toward, and positioned proximate to, the biological feature and after the lid assembly, in use, selectively covers, at least in part, the distal face of the open lumen in such a way that the lid assembly, in use, vaporizes a portion of the biological feature.
8 . The apparatus of claim 7 , wherein:
the distal face is configured to selectively emit energy.
9 . The apparatus of claim 7 , wherein:
the elongated medical needle is configured to house the lid assembly.
10 . The apparatus of claim 7 , wherein:
the lid assembly includes a wire with a coiled distal end.
11 . The apparatus of claim 7 , wherein:
the lid assembly is configured to be selectively movable from a covering position to an exposing position in which the lid assembly exposes, at least in part, the distal face of the open lumen in such a way that the lid assembly, in use, permits selective fluid communication between the open lumen and the biological feature after the lid assembly, in use, selectively exposes, at least in part, the distal face of the open lumen.
12 . The apparatus of claim 7 , wherein:
the lid assembly is operatively mounted at the distal face of the open lumen of the elongated medical needle.
13 . The apparatus of claim 7 , wherein:
the lid assembly includes:
a shaped wire structure with a coiled distal end; and
the shaped wire structure presents a coil-shaped active surface configured to vaporize a circular area of the biological feature.
14 . The apparatus of claim 7 , wherein:
the lid assembly includes a shaped wire structure; and
the elongated medical needle is configured to house a shaped wire structure.
15 . A method of emitting energy toward a biological feature of a patient, the method comprising:
maneuvering and positioning a distal face of an open lumen of an elongated medical needle toward and proximate to the biological feature of the patient; and
selectively covering, at least in part, the distal face of the open lumen with a lid assembly; and
selectively emitting energy toward the biological feature from the lid assembly after the distal face has been maneuvered toward, and positioned proximate to, the biological feature and after the lid assembly, in use, selectively covers, at least in part, the distal face of the open lumen in such a way that the lid assembly, in use, vaporizes a portion of the biological feature.
